早上好！!!!


我有一个表单（frmDialogForm），我从父表单（frmParent）打开。我打开frmDialogForm作为对话框，用户输入一些信息。用户单击具有DialogResult.OK的保存按钮。



当您单击保存按钮时，我想要做的是验证信息，如果用户输入的信息无效，那么frmDialogForm不会关闭。





Thanx ...

Good morning all!!!

What I want to do is validated the information when the you clicks the Save button and if the information inputted by the user is not valid then frmDialogForm does not close.


Thanx...

推荐答案

在你的frmDialogForm中订阅FormClosing事件并设置''FormClosingEventArgs''值，说e.Cancel = true;这不会关闭你的表单。



这里你可以做什么在frmDialogForm中保留一个布尔成员变量，并根据你的验证设置这个值为true / false以保持表格打开。

Subscribe the FormClosing event inside your frmDialogForm and set ''FormClosingEventArgs'' value say e.Cancel = true; which does not close your form.

what you can do here keep a boolean member variable inside the frmDialogForm and set this value true/false based on your validation to keep the form open.
